Feedback From The Judges


“Ranking such a diverse list of fantastic, innovative products & services has been both challenging and encouraging. It’s clear that we are finding technology solutions to a range of fundamental global problems, many of which have been invisible or unsolveable for a very long time. My choices reflect both their potential for positive impact and likelihood of adoption. I look forward to seeing how these technologies effect positive change in the crucial years to come, especially the top 10.”

–Tom Dunning, Founder and CEO at Ad Signal


“What impressed me the most is the range and diversity of the submissions, which include companies that have achieved sustainable transformation within their own operations, as well as technologies poised to deliver impact on a global scale. The submissions I have rated highest have the potential to make profound global contributions, particularly in addressing some of the most pressing challenges facing humanity today, including resource depletion and global warming. The top-ranked submissions feature credible business solutions with the capacity to have a significant impact at scale. These solutions are likely to gain traction swiftly and expand rapidly.”

–John Spear, MD at epi Consulting


“It is up to us, not future generations, to save the planet and I must congratulate the diverse range of Sustainability 60 entrants. They all play a crucial role. Those restoring or protecting nature, natural resources and promoting biodiversity must be particularly praised, including businesses providing alternatives to plastics, chemicals and other harmful materials. Without such action, even a ‘net zero’ scenario would be fatal. Increasing efficiencies and product lifespan is essential and innovations around waste reduction and recycling, give us a good chance to rewire our economies and provide a sound base to upscale new clean energy systems.”

– Nawaz Haq, Strategic Advisor to the General Secretary of the ZESTAs & Strategic Board Advisor to Space Aye


“This is my second year judging the Sustainability60 and it truly gets more difficult every time. At TechRound, we see hundreds of startups emerge every year with the sole aim of tackling climate change. To see so many amazing entrepreneurs put their business minds to this task is simply incredible. Congratulations to all of our finalists and also to the hundreds of companies that entered. You’re all doing very important work that is going to have a lasting impact on the world and we are incredibly proud to be celebrating you!”

– Dana Leigh, Editor at TechRound
